6mm Coppens Spirulina Pellets are a formulated diet for deep and especially intense colours in koi carp. Coppens Spirulina Pellets contain spirulina and are high in astraxanthin. Coppens Spirulina Pellets are flavoured with insect meal and have added vitamin A. Coppens Spirulina Pellets contain organic acids, Bio-Mas, and omega-3 rich algae. This carotenoid rich feed can be used in preparation for shows and contests. Because the white parts may discolour slightly, it is advised to switch to Health or Wheatgerm in the last month to make the white pure white again. These are floating pellets giving optical feeding control.
